I made an app for iOS for creating a social roster and setting specific catchup cadences for each friend. It's free, is purely local and has no backend, and was co-created by my wife and I. We've gotten a lot of value out of it, and it has measurably improved our lives. Try it out if you're interested!

Looks cool! Would you consider making the app available in the eu app stores?
